ADJUSTABLE HEADLIGHT Filed Aug. 6, 1929 2 Sheets-Shee 2 Attorney Patented Mar. 10, 1931 UETED STATES HARVEY L. LAIPIE'LE,OF AcKLnY, IOWA ADJUSTABLE Application filed August 6,

This invention relates to the broad class of electrical illumination and has more particular reference to adjustable headlights which are expressly but not necessarily intended to be used on a tractor to facilitate work at night in the fields.

In accordance with my idea, I provide a suitable support which is mounted on the tractor within convenient reach of the operator, said support being constructed toaccommodate a pair of oppositely disposed head lights having a universal mounting and operating devices therefor whereby to permit said headlights to be independently adjustlli able the direction of the adjustment being in a vertical plane or about a vertical axis, in a horizontal plane, whereby to permit the lights to be pointed so that one will project its beam forwardly and one will project its beam rearwardly, as to permit the beam ,to be arranged at the desired angle and direction to show the way ahead and to show the work completed.

I In accordance with the invention, I have provided what I believe to be a simple and economical headlight structure which is practical and will fulfill the requirements of a structure of this class in a highly satisfactory manner, the same being unusually eiiicient and desirable for the class of work enumerated but being adaptable for use in other lines of industry.

The particular structural details and their association and arrangement will become more readily apparent from the following description and drawings.

In the drawings:

Figure l is a top view of a headlight structure made in accordance with the present invention.

Figure 2 is a central vertical sectional view, the section being approximately on the plane of the line 2-2 of Figure 1.

Figure 3 is a cross sectional view on the line 3-3 of Figure 1.

Figure 4 is an inside elevational View showing the operating handle arrangement.

In carrying out the invention, I provide a suitable support generally designated by the reference character 5 and this comprises a HEADLIGHT 1929. Serial NO. 383,396.

suit'able'base 6 and an upstanding vertical wall Mounted on the base are two distinct headlights, one of which is distinguishedby the reference character 8 an'd the other by the reference character 9. These areidentical 55 in construction and consequently the same generally represented by the reference character 15. This comprises a semi-circular portion 16 which is vertically disposed in a normal condition, and a horizontal V-shaped portion 17. On the apex of'the last named portion 17 is a universal joint '18 carrying a link 19. On the central bottom portion of the part 16 is a socket 20 which joins to'a ball on a bracket 2l,constituting a universal ball joint mounting generally designated by the reference character 22.. This allows the frame to be tilted around the verticala'xis to swing the-beam in a horizontal plane and also'allow the frame to be tilted forwarder backward or to allow the beam to be raised and lowered in a vertical plane. Thus, a' substantially universal mounting of frame and light is provided. The lights 8 and 9 are operated for swinging the beam in a horizontal plane through the medium of separate abraiding rods 23 and 24-, extending through guides 25 on the panel board 7. These have individual handles 26 and 27 of appropriate construction. Obviously, by grasping the handle 26 and pulling it in or out, the light 8 will be manipulated for adjusting the handle 27 and operating it in a similar direction to enable the light 9 to be independently adjustable in a horizontal manner.

The reference characters 28 designate the brackets supporting curvate guide tubes 29. These tubes are provided to accommodate wire operating members or rods 30, having individual operating handles 31 and 32 for actuating the lights 8 and 9 respectively in a manner to vary the angle of the vertical light beam.

When the light is adjusted so that the beam is straight ahead, it can be lowered so that the beams on a- 100 foot distance will drop 85 feet or fifteen feet ahead of the tractor. This is obtained by operating the controls 31 and 32 respectively. Having the light fixed so that the beam is straight head, the light can be turned to the side so that the beam of light will be at least fifty feet from the riginal straight ahead position. This range is obtained by actuating the handles 26 and 27, in the manner already described. 1: The light. when in operation, will. give a beam of light ahead and also in back of the .machine so that the operator can see where he is going with his tractor and at the same time have a light to see the work he is doing in back of the tractor. The light is especially helpful in any way which requires motion of the tractor in the field, at night.

It is thought. however, that persons skilled in theart to which the invention relates will be able to obtain a clear understanding of the same after considering the detailed descrintion in connection with the drawings.

Therefore a more lengthy description is believed to be unnecessary. Min or changes in 3Q shape. size and rearrangement of details coming within the field of invention claimed may be resorted to, in actual practice, if desired.

I claim: In a structure of the class described a base, 5 a universal joint mounted on said base. and a frame including asubstantially semi-circular portion attached to said universal joint and also including a substantially horizontal V- shaped portion, a universal joint mounted on m the apex portion ofsaid V-shaped portion and including an operating link and a pushpull operating rod connected with said link, a headlight mounted on said frame, a relatively stationary bracket, a guide tube carried by said bracket, and a push-pull wire operating rod slidable through said tube and operatively connected at one end with the headlight whereby to permit both vertical and horizontal adjustment of the headlight. In testimony whereof I aflix my signature.
